MEMORANDUM
DATE: January 20, 2021
TO: Mayor and Councilmembers
THRU: Darin Atteberry, City Manager
Jackie Kozak Thiel, Chief Sustainability Officer
Lucinda Smith, Environmental Services Director
FROM: Cassie Archuleta, Air Quality Program Manager
RE: 2020 Air Quality Monitoring Data and Program Update
The purpose of this memo is to summarize 2020 air quality data as measured for two major pollutants,
ozone and particulate matter related
efforts.
Bottom Line
In many ways, 2020 has been a year of unprecedented extremes. The COVID-19 pandemic has
highlighted the importance of protecting those with respiratory or cardiac issues, as these individuals
are the most susceptible to both COVID-19 and air quality impacts. Early in 2020, Stay-at-Home orders
led to some of the cleanest days on record in 20 years, likely due to decreases in vehicle use. In
contrast, during the Fall and Winter, local and regional wildfires led to some of the poorest air quality on
record. Air quality is a Council priority, and the City has supported continued efforts at local and
regional levels to improve air quality.
Background
Air pollution is made up of gas or particle substances in the air that can be invisible to the eye and have
adverse effects on human health and the environment. Two of the pollutants monitored in Fort Collins,
ozone and fine particulate matter, have Federal air quality standards. Monitored data, real-time visibility
camera images and air quality alerts are available at www.fcgov.com/aqdata. In 2018, Council named
improving air quality as a top priority; with a focus on ozone, radon, particulate matter and mitigating
impacts from oil and gas sources.
2020 Data Summary
Air Quality data can be summarized using an Air Quality Index (AQI) which is used by the EPA to
communicate real-time air quality and health implications based on monitored values. The table below
summarizes the number of days that were measured for each pollutant by AQI category in 2020.

For ozone:
Eight (8) -hour averages). When
pollution levels are in this category, some members of the public may experience health effects,
especially members of sensitive groups such as the elderly, children and those with heart or
lung conditions.
These high ozone days are typical in Fort Collins during the summer months, where much of the
Northern Front Range does not meet national air quality standards for ozone. The region has
violated Federal ozone standards - since 2016.
High values are generally measured on warm, sunny, stagnant days, when emissions from
sources such as vehicles (local) and oil and gas production (transported) mix in the atmosphere.
For fine particulate matter:
Eleven (11) days in 2020 measured , and 1 day as
nhealthy . These indices are based on 24-hour averages, and do not reflect some of the high
values observed over shorter periods of time.
These measurements were augmented by several low-cost monitors throughout the community,
which also provided community access to more localized, real-time information.
The lowest fine particulate matter averages in over 20-years were measured in March 2020,
likely associated with a decrease in gas and diesel vehicle use associated with COVID-19
related Stay-at-Home orders.
The highest fine particulate matter averages in over 20-years were measured between August
and October, with values impacted by large regional wildfires
Regional and Local Air Quality Improvement Efforts
The City works locally and regionally to reduce pollutants at the source, promote awareness, and
increase resiliency. Specific efforts in 2020 included:
Education and outreach efforts regarding air quality were updated to address the compounded
risk from COVID-19.
Enforcement of new restrictions (curfews and distance requirements) for outdoor solid fuel
burning in residential areas to reduce localized smoke impacts (fine particle emission). Burning
was fully prohibited by executive order during the worst regional fire impacts (8/31/20-11/18/20).
Regionally, due to the Federal non-attainment status for ozone, the Regional Air Quality Council
(RAQC) adopted a new State Implementation Plan (SIP) with new State regulations to reduce
emissions that contribute to ozone.
reducing municipal small-engine (e.g., lawn and garden equipment) and large engine emission
sources.
The City participated in rulemakings at the State level related to ozone non-attainment, regional
haze (related to particle emissions) and oil and gas sources.
Next Steps
In 2021, some highlights of anticipated air quality related efforts include:
Promoting air quality awareness with streamlined communication of Air Quality Alerts, including
Spanish translations.
Increased indoor air quality outreach efforts targeting strategies such as ontaminant
free , especially as people continue to spend more time in their homes.
Partnership with CSU and City and County of Denver on air quality monitoring grant proposals
intended to increase local and regional air quality monitoring.
Continued efforts to reduce vehicle and small engine emissions, including rebates for recycling
inefficient small gas engines such as older lawnmowers.
